Description
Technical Field
The invention relates to the field of server firmware, in particular to a method, a device, equipment and a storage medium for dynamically configuring a BIOS character string.
Background
In the modern times, due to rapid development of science and technology and society, the application of IT technologies such as internet and big data is more and more extensive, and a server is used as an important infrastructure of the technologies, so that a large amount of deployment and application are obtained, no matter whether calculation or storage is carried out, the dependence on a server system cannot be avoided, and most of data used for exchange and processing are also stored in the server. With the increase of server manufacturers and the refinement of client applications, in recent years, more and more server clients put forward different customized demands for server products, such as personalized design and implementation of the whole server, and private customization of a character string, even a plurality of indexes are included in the range of collection tests. Therefore, for server design and manufacturers, how to make a product meet the requirements of different customers as much as possible becomes an important design consideration.
Currently, System Management BIOS (SMBIOS) character strings in most Basic Input Output Systems (BIOS) of servers already support static modification by a tool provided by an Independent BIOS Vendor (IBV), but need to be modified one by one; some of the strings may be designed to be read from Field Replaceable Unit (FRU) information of a Baseboard Management Controller (BMC), but the FRU defines only a limited string, and cannot be updated by the BMC if the FRU does not include the string. However, many clients require personalized batch update of BIOS strings other than FRUs at present, some BIOS strings even cannot be modified and satisfied by IBV tools, and server manufacturers often reuse existing server products or BIOS versions as much as possible in order to reduce development cost, save labor, satisfy different customization requirements of different clients, and facilitate version management.
The default of character strings displayed in the server system BIOS is stored in the BIOS file of the server, the character strings are generated when the BIOS is compiled, if the character strings are required to be changed, the first method is to modify the BIOS code again and generate a new BIOS file; in the second method, if the character string can support IBV tool modification, the tool can be installed in the system environment of each machine for corresponding modification; third, if the string exists in the FRU, the string may be updated by the FRU. For the BIOS strings outside the FRU, no matter recompiling the BIOS code or modifying the BIOS strings by using the IBV tool, the requirements of all clients for personalized customization and batch deployment cannot be met, the management and control cost of the server manufacturer version and the time investment of software research and development personnel can be greatly increased, the software research and development cost is increased, and the costs of the test personnel and the time of the client operation and maintenance are also increased.
